[Harmless Teddy Bear]

Seems kind of harsh. I mean, sure, he was drunk, but at least he wasn’t driving... and what’s the big deal about a bike going through the drive through?

Same reason that you can't walk down the middle of a road to answer your second question.

To answer your first, because he wouldn't leave and was blocking the lane.

It was 3 am, how many cars was he blocking?

Probably was a 24 hour place with drive-thru only in the wee hours and he wanted some rocket fuel for the trip home.
